To aZZ whom 'aft 'may cov/mem.

(Be it known 'that l, ERNEST E. Hninrz,

a citizen of the United States, residing at Detroit, in the county oi Vfayne and State e or' lilichigan, haveinvented certain new and useful improvements in Window Regulators,

of which the following is a specification.

This invention relates to window reg ulatorsn it is the object 03E the present invention 'to provide a Window regulator of relatively simple construction; this permits it he economically huilt and opens a use `lor it on cheaper cars which have heretofore not been provided with Window regulators.

nrtherniore, the regulator is so constructed and arranged that the handle may he installed at a variety of points across the door or Window. This permits the proper placement of the regulator handle to meet 2o with the requirements of the particular Window or door. This and other features will more folly appear in the description following.

ln the drawings- Fig. lY is a side elevation of a door containing)` the regulator, the trimming being removed.

Fin'. 13 is a section on the line T13-13 of Fig. 2.

The regulator is provided with the usual cross-strap freine a which carries at its loottom a nlley Wheel b mounted on the carrier c Wlioi is provided with a pivot pin d (Fi d) ley which it may both pivot 4and sli e derlei No. $53,724.

through the ears e struck ont of the strap trarne a. The coil sprin f forces the pulley wle-eel carrier downward y 'and consequently serves to tension the cable g This con struction is described and clailned in the copendingr application No. 583,723.

rlhe cable has its two ends fastened to the elongated drum la. One end Winding around the drum in one direction and the other end Winding around the drum in the opposite direction, as is plainly shown in Fig. ll. Consequently when the elongated drum is turned in one direction, one end ot the cable unwinds and the opposite end Winds up and vice versa, when the elongated drum is turned in the opposite direction. This construction eliminates an expensive chain and sprocket Wheel. The elongated drum is nothing more than a common curtain roller provided with a tensional spring i, anchored at one end to fthe curtain roll and at the other end to the stationary shaft y' (Fig. ByT releasing the paiyl le the ratchet Wheel m may he turned to adjust the spring z. The spring z' is a counter-balene; ing spring which is desirable inv Window' regulators to make the Window raise substantially as easy as it lowers.

One otthe very important features of this regulator is the arrangement of the elongated drinn with the keyvvay n in which the spiral gearo is loosely splined. Hence the spiral gear o may be freely slid along theA elongated drum to any desirable position where the gear housing` p is located.

ln connection with rear uarter windows and the various door win ows in an enclosed body, it is necessary very often to locate the regulator handle at dierent points, consequently lwith .Ordinary regulators it requires a different regulator construction for the several parts of the car. With the 'resent construction, the housing p may e secured by screws to the lock board g at any point along the regulator plate which is secured to the lock board y. The lrey z is shown clearly in Fig. 3 and is secured to the wor The spiral gear lr vmeshes with the spiral gear o and is rotatably supportedl in the housing p of the regulator. I

This housing is secured to the inside of lill@ the supporting late s by the screws t. The regulator hand e u serves to turn the worm gear r. A clutch 10 may be interposed benecessary will depend altogether on' thel pitch arrangment of the teeth of the spiral gears. If t e pitch is small, .the arrangement will be substantially irreversible and consequently no clutch` is necessary. This arrangement ma be adopted but the regulator handle wi l have to be turned a ood many times to raise and lower the win ow; if a less number of turns of the handle is desired to raise and lower the window, then a clutch should be used.

What I claim is;

1. In a window re later, the combinationof a flexible dreigtu member, upper and lower rotatable members over which the flexible draft member runs, and an actuating mechanism for the upper member which maybe permanently stationed in various ositions with respect to the draftmember aterally alon the door or windowfor the purpose speci ed.

2. In a window regulator, the combination of a flexible draft member, upper and lower rotatable members over which the flexible draft member runs, and a driving mechanism for the upper rotatable member adjustably fixa-ble at various points along aicl rotatable member for the purpose speci- 3. In a window regulator, the combination of a iiexible draft member, a lower rotatable member over which the flexible draft member runs, and a driving mechanism having a drive connection with the upper rotatable member which permits the driving mechanism to be slid along the upper member to fix said driving mechanism at various positions to accommodate the conditions met with in the body.

4. Inv a window regulator, the combination of a flexible draft member, an up er and a lower rotatable member over which the flexible draft member runs, and a driving mechanism adjustably fixable at various points across the door or window by reason of having a slidable splined connection with the upper rotatable member.

5. In a window regulator, the combination of a flexible draft member, a lower pulley'wheel over which the same runs, an upper elongated drum around which the draft member winds, and a drivingl mechanism for the upper drum adjustable to various plonts along the drum for the purpose speci.-

6. In a window regulator, lthe combination of a flexible draft member, a lower pulley wheel over which the same runs, a transat various points along the elongated drum,

the driven member sliding along the drum to accord with such positioning.

8. In a window regulator, the combination of a iexible draft member, a lower pulley Wheel over which the draft member runs, an elongated transversely extending drum over' which the draft member winds at the top, a spiral gear splined on said drum to be slidable therealong, and a driving gear having a driving connection with the vspiral gear and which may be placed at various points along the drum by reason of the splined relation of the gear on the drum.

9. In a window regulator, the combination of a lower rotatable member, a iexible draft member running thereover, an upper elongated drum over which the two upper ends of the fiexible member wind in opposite directions, a driven member slidable along the said drum and having a driving connection therewith, and means supportable at various positions'along the drum for driving the driven member.

10. In a window regulator, the combination of`a lower rotatable member, a flexible draft member running over said member, an upper elongated -drum over which the dexible draft member winds in opposite direccurtain roller type locatable directly underI the window opening, means for positively rotating said drum inl either direction, a coiled spring contained in the said drum for equalizing the work of the rotating means in the upward and downward travel ofthe Window sash, the said draft member having its ends winding in opposite directions over the drum and a device on an intermediate portion of the flexible'draft member for connection with the window sash.

12. In a window regulator, the combination of a flexible draft member, a lower pulley over which the same runs, a drum of the curtain roller type locatable directly under the window opening, a gear secured to the memes dium to rotate the same, a driving gear oi rotating the first mentioned gear in either direction, n coiled spring contained in said drum for equalizing the Work of the gears in either direction, the said draft member having its ends Winding'in opposite directionslover the drum and a device on an intermediate position 'of the exibi@ me; member for connection with the Window sash. i'

In testimony whereof I affix my signature.
